Thank you very much for conducting this test! I just saw the comment response notification about your question regarding agitation on the previous video, I apologize for not getting back to you in time, things have been unusually busy this week. The timeframe in which this video was released took me a little off-guard, too 😅that's a good thing though. Yes I did forget to mention that I typically do an "Ilford" agitation of 30 seconds constant, then about 4 inversions per minute. It occurs to me that this might have helped with density range for printing, but would it have taken it to a 'fuller' range, I'm unsure. I'd like to have your opinion on that! I now realize that I should've also given the information that I do more scanning than printing, whoops! All in all this is very valuable data. This prediction for a new film wasn't as on-point as with the previous 2, but I'm happy that the number it spewed me was in the ballpark. When I have more free time I'll try to push the formula to see if I can adjust it for different devs with new films, and if that works, different films with new devs. The dream would be to have a calculator tool which would help drive adoption of new products. One thing I've seen with P33 was that some folks were waiting for Massive Dev Chart times to test the film themselves in their favorite chemistry which I understand with the price of film these days, but things could be better. And while Ferrania could've done a little bit more IMO with regards to giving times for a bigger variety of developers, I understand that they're a very small player with a constrained budget and staff. If I can't make the general idea work, I will, at the very least, publish the one equation for BW&G though! Thanks again Andy! Cheers from Montréal
Oh, I forgot to mention, having the Base+Fog be higher than with Xtol is interesting. I've experienced intense fogging with well-expired films in BW&G, it's the one situation I avoid using this dev completely. Could be the effect of a higher concentration of triethanolamine as the sole source of alkalinity. In all cases it's a little more surprising to see 0.53 on a brand new film... I should get a densitometer too some day!
Increasing the agitation to 4 sec every half minute would increase the contrast. It would be interesting to test this to see the difference. I would definitely love to see your equation when you've got it all worked out. Your calculated time is definitely in the ballpark. It's very acceptable for scanning. Now, I await 120 P33. By the way, I LOVE Montreal. I visited about 10 years ago. What a vibe! Art! Photography left right and centre. Cheers!

'leave phone upstairs" ;P lol!
